In order to keep vegetables "crisp", grocery stores use cool water or ice
Homework Answers
Technically, distilled water. Osmotic pressure will draw water across the cell wall from an area of low salt concentration to an area of high salt concentration. By definition, distilled water has (almost) zero dissolved salts, so water will flow into your veggies, keeping them nice and crisp.
Theoretically, at least. In reality, I doubt the difference in concentration of dissolved salts between distilled and tap water would make a noticable difference.

Take To - 20°C In order to cool 1 ton of water at 20°C in an insulated tank, a person pours 64 kg of ice at -8°C into the water. Given the melting temperature and the heat of fusion of ice at atmospheric pressure are 0°C and 333.7 kJ/kg, respectively, determine (a) the final equilibrium temperature in the tank (Round to two decimal places) and (b) the exergy destroyed during this process. X destroyed kJ (Round to the nearest integer)...

Prior to the advent of refrigeration, many different methods were used to keep food cool and prevent it from spoiling. One common method was to use clay pots. In this approach, two clay pots, an inner pot and an outer pot, were separated from each other with a thick layer of wet sand in between. The inner clay pot would cool if the atmosphere was dryallowing the food placed inside to stay cool. a. What was happening to allow the...

than other labs. These are toxicity, volatility, and flammability. We routinely use toxic organic solvents like methanol and acetone that are volatile (have low boiling points), but even solid organic materials can produce vapors that may be toxic. Furthermore, organic materials are flammable, and solvent vapors in the air can and do produce explosive mixtures.
